All three of these are small letters on US Coins used to identify which mint they were made at. Most commonly D stands for Denver but it could also stand for Dahlonega. Between 1838 and 1861 gold coins were made at this mint. O stands for New Orleans and CC stands for Carson City.
Look on the back below the DO in DOLLAR. It could be black or there could be a small O, S, or CC mintmark. Value as of June 2012: No mintmark:$52 "O" mintmark:$156 "S" mintmark:$52 "CC" mintmark:$540
If you mean a "Mintmark"? They are small letters ( O, S, CC & D) on the reverse of the coins.
Any mintmark will be found on the reverse of the coin under the wreath above the space between the D and O in "DOLLAR". Keep in mind that your coin could have no mintmark, in which case it would be minted in Philadelphia. If your coin has a mintmark, it will ether be a "CC", a "S" or an "O".
IF it doesn't have a mintmark above the DO in dollar it means that it wasn't made at Philadelphia. It could be a O, S, or CC. O= New Orleans S= San Francisco CC= Carson City
First you need to check the back, above the "DO" in DOLLAR, for a mintmark. There may be a small "O", "S", or "CC" there. There may also be nothing there. In average circulated condition, with a "CC" mintmark, it's worth $80-$100. With any other (or no) mintmark, it's worth $8-$10 In almost uncirculated condition, with a "CC" mintmark, it's worth about $200. With any other (or no) mintmark, it's worth about $15 An uncirculated coin will be worth about $400 with a "CC" mintmark, $40 with an "O" mintmark, or $20 with an "S" (or no) mintmark.
I'm assuming that you are referring to the Morgan Dollar, 1878-1921. The mintmark (D, S, CC, or O) appears on the reverse of the coin underneath the eagle.
June 2011 If it has no mintmark this coin in that condition is worth $71. If it has a CC mintmark it is worth $570 If it has a O mintmark it is worth $70
The mintmark if it has one is in the same place on all Morgan silver dollars, it's on the reverse just above the letters DO in dollar. If it does not have a mintmark it was coined in Philadelphia no Morgan dollar has a "P" mintmark. The only mintmarks used on Morgans are O, S, CC and a D was used in 1921 only.
If the coin has a CC mintmark it will be on the reverse

On a US silver dollar, the mintmark is in a variety of locations, on a Morgan Dollar ( 1878-1921) it is underneath the tail feathers of the eagle between the D and the O in Dollar. On a Peace Dollar (1921-1935) it is located underneath the One in "One Dollar" on the reverse on an Eisenhower Dollar (1971-1978) it is between the 3rd and 4th numbers of the date by Eisenhower's neck. If there is no mintmark, the coin was minted in Philadelphia, if there is a D mintmark, the coin was minted in Denver, if there is an O mintmark the coin was minted in New Orleans, if there is an S mintmark the coin was minted in San Fransisco and if there is a CC mintmark the coin was minted in Carson City
Please look at the mintmark again. The Denver Mint did not exist in 1873, the only mintmark's it could have are "S" or "CC". Post new question.
